When Does a Foreign Company Need a Turkish Tax Opinion?
Nine situations where a CFO or general counsel should get the Turkish tax answer in writing — and three where an opinion is the wrong tool.
Key takeaways
- The question to ask is: “If the Turkish tax office challenged this in five years, what would we show them?”
- Auditors increasingly ask for written support on cross-border positions under IFRIC 23 and ASC 740.
- An opinion is fastest; a private ruling (özelge) binds the tax administration but takes longer.
- For routine, settled questions, a short email answer from your Turkish accountant is enough.

The 9 situations where you should get a Turkish tax opinion
1. Your first employee or long-term contractor in Turkey
The Turkish question is not just payroll. It is whether that person creates a permanent establishment — through a fixed place of business at your disposal (Tax Procedure Law Art. 156) or by habitually concluding contracts on your behalf (Art. 157). Our developer PE analysis covers the most common fact pattern.
2. Senior management living in Turkey
If board decisions are effectively taken in Turkey, the place of effective management (iş merkezi) can move here and make the whole company a Turkish taxpayer (Corporate Tax Law Art. 3). This is the highest-impact question we see and the one most often missed.
3. A Turkish customer withholds tax from your invoices
A 20% deduction usually means the payer classified your fee as a professional service or royalty. If it is business profits, or if a treaty applies, the deduction may be wrong or too high. See how to apply a Turkey tax treaty to a payment.
4. You sign a distribution, licence or services contract with a Turkish party
Tax clauses — gross-up, who bears withholding, VAT, stamp duty — are cheapest to fix before signature.
5. You charge intercompany fees to a Turkish subsidiary
Management fees, cost allocations and IP charges raise deductibility, withholding, reverse-charge VAT and transfer pricing questions at the same time.
6. Your auditor asks for support on an uncertain tax position
Under IFRIC 23 and ASC 740, management must assess whether a position is likely to be accepted. A written opinion with a stated confidence level is the standard evidence.
7. You are buying, selling or investing in a Turkish company
Seller-side gain, target exposures and post-deal structure each need a Turkish view the SPA can rely on.
8. Your sales to Turkey move into digital services
Digital services tax, VAT registration for B2C e-services and withholding on B2B software fees interact. See digital services tax in Turkey.
9. The Turkish tax office writes to you
An invitation to explain (izaha davet, Art. 370) or an audit letter needs a technical position paper quickly. An opinion becomes the backbone of the response.
When you do not need a Turkish tax opinion
- Settled, routine questions — the current VAT rate or a filing deadline. Ask your accountant.
- Positions that will repeat for years at high value — consider a private ruling (özelge) instead, possibly with an opinion covering the waiting period.
- Pure legal questions — corporate law, employment law, licensing. These need a Turkish lawyer.
Opinion vs tax memo vs özelge: which do you need?
| Short tax memo | Written tax opinion | Özelge (private ruling) | |
|---|---|---|---|
| Purpose | Internal orientation | Decision, audit file, third-party reliance | Administrative certainty |
| Signed by | Adviser | Licensed CPA, with assumptions and confidence level | Revenue Administration |
| Binds the tax office? | No | No | Yes, for the applicant on the facts given; not the courts |
| Time | Days | Agreed delivery date | No statutory deadline |
Detailed comparison: Turkish tax opinion vs özelge.
How to ask the right question
A good opinion starts with a precise question. Send:
- The entities and their countries of residence.
- What happens in Turkey: people, activities, days, contracts signed, where.
- Money flows: who pays whom, for what, under which contract.
- Who will read the opinion (board, auditor, buyer, tax office).
- The deadline and what decision it feeds into.
What drives the cost of a tax opinion
We quote fixed fees after scoping and do not publish prices. The drivers are the number of questions and taxes, whether a treaty or third country is involved, document volume, how settled the law is, third-party reliance and the deadline. Details on the Turkish tax opinion service page.
How this compares with other countries
Germany (binding ruling under §89 AO), the US (private letter ruling) and the Netherlands (advance tax ruling) offer paid, formal routes to administrative certainty. Turkey’s özelge is free but has no deadline and applies only to the applicant. In practice that makes the written CPA opinion the main certainty tool for foreign companies with Turkish exposure — and the özelge a second step for long-term positions.
Case analyses
- Facts
- A Delaware company’s co-founder and CEO moved to Istanbul; board meetings were held online with the CEO dialling in from Turkey.
- The obvious answer
- “The company is incorporated in Delaware, so it is a US company.”
- Why that failed
- Turkish law looks at where the business is actually managed. With the CEO taking key decisions from Istanbul, the effective-management test under Corporate Tax Law Art. 3 was live.
- Structure adopted
- A governance protocol (where decisions are taken and documented), a second US-based director with real authority, and a signed opinion on residence for the next financing round’s diligence.
- Facts
- A Turkish customer withheld 20% from installation and training invoices.
- The obvious answer
- “We will claim a credit in Germany.”
- Why that failed
- The credit was limited and the underlying classification was disputable; nobody had provided a German residence certificate.
- Structure adopted
- An opinion splitting the contract into supply, installation and training components with the treaty treatment of each, a residence certificate procedure for future invoices and a refund analysis for the past.
What happens if…
What happens if we ignore the question and nobody asks?
Turkish exposures usually surface later — in a tax audit, a buyer’s diligence or an auditor’s review — when five years of tax, a 100% tax loss penalty and late-payment interest may be at stake.
What happens if our Turkish customer insists on withholding?
The payer bears the liability if it under-withholds, so it will be cautious. A written opinion plus a valid residence certificate is usually what changes its position.
What happens if the law changes after the opinion?
The opinion speaks at its date. We flag pending changes we know about and can update the opinion if the law moves.
Frequently asked questions
When does a foreign company need a Turkish tax opinion?
When a decision, payment or audit file depends on a non-obvious Turkish tax position — for example a first hire in Turkey, a Turkish customer withholding tax, intercompany charges, a treaty claim, a transaction or a tax office letter.
Can a company without a Turkish entity get a Turkish tax opinion?
Yes. An opinion addresses the company’s Turkish exposure; no Turkish company or tax number is required.
Is a Turkish tax opinion the same as an özelge?
No. An özelge is a private ruling issued by the Turkish Revenue Administration under Tax Procedure Law Art. 413. A tax opinion is a professional’s written analysis and does not bind the tax office.
Why do auditors ask for a Turkish tax opinion?
Under IFRIC 23 and ASC 740, management must assess uncertain tax positions. A written opinion with a stated confidence level is standard supporting evidence.
How long can the Turkish tax office go back?
Generally five years from the start of the year following the tax year concerned (Tax Procedure Law Art. 114).
What should I send to get a Turkish tax opinion?
The entities and countries, what happens in Turkey, the money flows and contracts, who will rely on the opinion and the deadline.
